What is an Y-sustain board?

Y-sustain boards are found in plasma TVs and drive all of the Y-axis video signals coming from the logic board to your TV screen.

Which symptoms does an Y-sustain board fix in a TV?

• If your TV has has no video, then the Y-sustain could be bad.

• If your TV doesn’t turn on, then the Y-sustain could be bad.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace an Y-sustain board?

While replacing the Y-sustain board is pretty easy, you’ll want to be mindful not to tear the flat ribbon cables when connecting/disconnecting the board.

We recommend matching the part number on your original part with the part number listed on this page to ensure compatibility.

While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.

We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.

Please don't hesitate to contact us with any questions. We're here to help!
